T 0 all whom it may concern:

Be it known that I, EM'IL Bosnmion, a citizen of Germany, residingld-armen, Germany, have invented certain new and useful Improvements inSingle-Thread Bone Laces and Processes of Making the Same, of which thefollowing is a specification. 7

My invention relates to a machine-made "imitation Valenciennes laceanclto an improved process of making the same on the so-calledsingle-thread 'p l-aitin-g machine, that is a machine of the typegenerally described in the U. 3. Patent No. 613,380 to lVIalhr-e.

The manufacture of machine plaited laces has been perfected in recentyears to such an extent that almost all kinds of bobbin or pillow lacesmay be manufactured by means of the above named single thread plaitingmachines, a product being thereby obtained which can hardly bedistinguished from the genuine hand-made laces.

One of the few exception was the manufacture of the very delicateValenciennes laces of great delicacy, because the working of threads ofthe desired fineness upon the plaiting machine presents difficulties onaccount of the likelihood of frequent breaking of the threads. It becamenecessary, therefore, in the manufacture of such laces by machinery toemploy threads of greater thickness, so that the laces manufactured inthis manner were lacking the exceedingly delicate clear ground peculiarto the handmade goods which latter on account of their fineness oftexture were particularly highly valued and were noticeable by theirbeing hand-made.

According to my invention provision is made to overcome this difiicult'yby composing the ground of the new machineqnade imitation Valencie'nneslace of this invention which is to be manufactured on the single threadbone-lace machine from individual braids which instead of the fourcomponent threads ordinarily employed consist of only three threadsplaited together, and in consequence thereof I am enabled withoutexcessive weakening of the individual threads to produce a ground withplaited meshes of a fineness and clearness heretofore impossible toobtain on machines, and which is peculiar only to the most delicatehand-made Valenciennes laces. 'Ihus I obtain a lace which, thoughdiffering an the number of threads from the real article, hassubstantially the same appearance 1 as the genuine Valenciennes l'ace,because the (difference or threads in each braid will not be noticed bythe naked eye. There is,

moreover, the additional advantage that as a result of this novelformation of laces far less bobbins and consequently smallersizedmachines, and less thread material than heretofore are required for themanufacture of such laces by machinery.

In order .to make it possible with the lace ground (thus produced toalso obtain the usual spiders, ribbons and similar patterns, which, inValenciennes lace, are as .a rule worked in a weave-like manner, thethreads of the braids of the lace ground are at every place where apattern is to be formed redistributed into groups of two, four or anyother even number of threads which are then utilized in the well knownmanner for the formation of the patterns.

I have shown my invention as embodied in a piece of lace on theaccompanying drawing by way of example.

Figure 1 shows a lace produced in accordance with my invention in itsnatural slze.

Figure 2 is part of the same lace on a greatly enlarged scale.

In the drawing :a indicates the ground formed in the manner of the usualValenciennes-laces the individual meshes of which are approximatelydiamond-shaped. The sides of the diamond are formed by single braidswhich, as shown in Figure 2 of the drawing, are each composed accordingto my invention of only three braidingly connected threads, I), 0, d,plaited together, while in the Valenciennes laces thus far known theyconsist of four threads each. At certain points spaced from each otherthe individual braids are connected to each other by the mutualinterchange of two pairs of threads, as illustrated at f as a result ofwhich the braids are caused to run in zig-zag lines, thus forminglongitudinal rows of diamond-shaped meshes. The interconnection of thebraids may also be effected by the interchange of only one or of allthree pairs of threads, and I do not de sire to be limited to theinterchange of two pairs of threads only. It is important, however, thatbraids or tyes which form the substantially diamond-shaped meshesconsisteach of three, and only three threads plaited together.

For the formation of the usual pattern,

1 thus for instance of a spider z', the threads which form the braidsare at the respective place redistributed into groups g, g of only twothreads, and they are then interlaced in a substantially weave-likemanner for the formation of the pattern. According to the kind ofpattern it isdesired to obtain I may alsoassemblefour or six threads, asshown for instance with reference to the composition of the ribbon h.

."The invention is susceptible of 'a great many difierent applicationsand-it mag be of varied and modified to suit the kin goods to which itis employed and without deviation from the spirit thereof.

I claim Y 1. A machine-made imitation Valenciennes lace comprising aiseries of braids consisting each of three, and only three threadsforming a plait or queue, said braids being arranged in zig-zag linesand connected at their meeting points by a mutual in- ,Valenciennes laceon the single-thread plaiting machine comprising the steps of producinga ground with substantially diamond-shaped meshes by formin a series ofbraids by plaiting together three, and

only three threads each, and interconnecting said braids at certainintervals, and producing patterns by redistributing the threads whichform said braids into groups of an even number of threads andinterlacing said threads in a substantially weavelike manner.

In testimony whereof I aflix myzsignature.
